Cardiac disease in intracerebral hematomas

Abstract

The Central Nervous System (CNS) plays an essential role in the regulation of the cardiac function. There is strong evidence that many CNS lesions, mainly those of hemorrhagic origin, may induce repolarization abnormalities and enlargement of the QT interval (ECG changes) and several types of arrhythmias. In some cases these changes have been related to sudden death. The imbalance between the sympathetic and parasympathetic systems, favoring the former, seems to be the etiopathogenic factor. We have carried out a study on thirty-two in-patients suffering from non-severe intracerebral hemorrhage, by means of a Holter ECG examination within the first 72 hours and a second record after two months. We have assessed any significative differences on the ECG findings in relation to the location of the hematoma (left or right hemispheres) and the presence of a personal history of arterial hypertension and/or heart disease. One or more ECG changes were present in 69.2% of the patients and 73% showed one or more rhythm abnormalities. There was a higher incidence of supraventricular arrhythmias associated with the right hemisphere hematomas, with an statistical significance for the atrial extrasystolia. No differences were found between t...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
